5.1.3. State Machine
The state machine describes the device status and the possible control sequence of the frequency
converter. The state transitions can be generated by using the “Control word”. The “Status word”
indicates the current status of the state machine. The modes INIT, STOP, RUN and FAULT corres-
pond to the actual mode of the Frequency converter.
NOTE! Always set CW bit0 to 0 after fault reset before proceeding!
